I have never tried seriously to take pictures of wild game while out hunting. These pix are from a photo trip to Jasper National Park in Alberta Canada. I lugged 15 or 20 pounds of photo gear up the hill with me. However, I think you may want to look into "digiscoping". This involves using almost any camera to shoot through a spotting scope...which you already have with you on your hunt.Digiscoping

Len, those are great pictures I have yet to get a sheep tag and they are my favorite animal to see out. They would make a great addition to my wall. The big horn is a hell of an animal . I really appreciate the pictures.

Using your scope is one way that will work in a pinch. One of our doe/hog hunters does this. He scouts for us at the same time. Here is a picture of a young 10pt with great genetics as an example. I think his camera is only 4x, but where the deer was standing is about 115yds. Notice the Javilinas in the background as well:
